Entanglement Research for the Coupled Superconducting Phase Qubit and a Two-Level System

open access: yesAdvances in Condensed Matter Physics, 2020
Entanglement can exist not only in the microscopic system (e.g., atom, photon, and ion trap) but also in macroscopic systems. According to recent research, entanglement can be achieved and controlled in superconducting devices.

Dynamics of entanglement of atoms with two-photon transitions induced by a thermal field [PDF]

open access: yesКомпьютерная оптика, 2020
In this paper, we investigate the entanglement between two two-level atoms non-resonantly in-teracting with a thermal field of a lossless one-mode resonator via degenerate two-photon transi-tions.

Quantum Correlation Dynamics in Controlled Two-Coupled-Qubit Systems

open access: yesEntropy, 2020
We study and compare the time evolutions of concurrence and quantum discord in a driven system of two interacting qubits prepared in a generic Werner state.

Entanglement breaking channels and entanglement sudden death [PDF]

open access: yes, 2016
The occurrence of entanglement sudden death in the evolution of a bipartite system depends on both the initial state and the channel responsible for the evolution.

Multipartite entanglement sudden death and birth in randomized hypergraph states [PDF]

open access: yesPhysical Review A, 2023
We introduce and analyze the entanglement properties of randomized hypergraph states, as an extended notion of the randomization procedure in the quantum logic gates for the usual graph states, recently proposed in the literature.

Dynamics of Entanglement in Jaynes–Cummings Nodes with Nonidentical Qubit-Field Coupling Strengths

open access: yesEntropy, 2017
How to analytically deal with the general entanglement dynamics of separate Jaynes–Cummings nodes with continuous-variable fields is still an open question, and few analytical approaches can be used to solve their general entanglement dynamics ...

Postponing the decay of entanglement and quantum coherence for maximally entangled mixed states under the action of correlated noise channels

open access: yesFrontiers in Quantum Science and Technology, 2023
We investigate the dynamics of a maximally entangled mixed state (MEMS) under the action of correlated noise channels. The channel acts in a way that its successive uses are correlated. We have studied the MEMS properties, including quantum coherence and

Effect of random telegraph noise on entanglement and nonlocality of a qubit-qutrit system [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics, 2017
We study the evolution of entanglement and nonlocality of a non-interacting qubit-qutrit system under the effect of random telegraph noise (RTN) in independent and common environments in Markovian and non-Markovian regimes.

Entanglement between two superconducting garge qubits

open access: yesВестник Самарского университета: Естественнонаучная серия, 2023
In this paper, we investigated the dynamics of entanglement of two identical charge qubits with Josephson junctions in the case when one of the qubits is exposed to a microwave field in a coherent or thermal state. We have found the exact solution of the

Time-invariant entanglement and sudden death of nonlocality for multipartite systems under collective dephasing [PDF]

open access: yesEuropean Physical Journal D : Atomic, Molecular and Optical Physics, 2016
We investigate the dynamics of entanglement and nonlocality for multipartite quantum systems under collective dephasing. Using an exact and computable measure for genuine entanglement, we demonstrate the possibility of a non trivial phenomenon of time ...
